【问题描述】：
我有一个 servlet，我试图将文件写入响应输出流。
response.setContentType("application/octet-stream");
String value = "attachment;filename=\"" + appName + "\"";
response.setHeader("Content-Disposition", value);
response.setContentLength((int) file.length());
response.setBufferSize(99999);
while ((length = fis.read(buffer)) > 0) {
sumBytes = sumBytes + length;
os.write(buffer, 0, length);
}
os.flush();
fis.close();
这对 http 很好，但是当我尝试通过 https 下载相同的文件时，会出现 SocketException。
我认为 https 连接在请求后立即关闭。
请为此提供解决方案。
这是一个例外。

【问题讨论】：
-
在 https 服务器中，证书是由第三方签名的有效证书还是自签名证书？
-
您需要告诉套接字接受该自签名证书。
